I found it too sensitivy to control the plane with warthog at deadzone 0. I still haven't founded my optimal settings. The thing is when I'am after the enemy plane and getting it to my crosshair my plane overreacts. Sure I need more flight hours to get comfortable with the stick and plane but the thing I'am saying go and try to change them.
Start adjusting like 0.10 on both and go fly check the difference.
Fly safe
